Trade tensions threaten global growth as the engines of leading economies fall out of sync, the world’s top finance chiefs warned on Sunday.

Global growth remains robust and many emerging-market countries are better prepared to face crises, but risks to the world economy have increased, finance ministers and central bankers from the Group of 20 nations said in a statement published at the end of their two-day summit in Buenos Aires.

While Australia and Canada said the US remains committed to free and open trade, Europeans had tougher language for the US administration on trade.

French Finance Minister Bruno Le Maire over the weekend urged the US to return to reason and said the EU would not negotiate trade issues “with a gun to the head”.

Officials said they reaffirmed their exchange rate commitments made in March, when they pledged to refrain from competitive devaluations.

Prospects of an intense debate on currencies had dramatically increased on Friday when Trump accused the EU and China of manipulating their foreign exchange rates to obtain trade benefits and said a strong dollar and rising Fed interest rates were undermining US competitiveness.

Mnuchin said at the weekend that Trump was not trying to intervene in the currency market and fully supported Federal Reserve independence.
